El Infiernito, (Spanish for "Little hell"), is a pre-Columbian Muisca site located in the outskirts of Villa de Leyva, Boyacá Department, Colombia. It is composed of several earthworks surrounding a setting of menhirs (upright standing stones); several burial mounds are also present. The site was a center of religious ceremonies and spiritual purification rites, and also served as a rudimentary astronomical observatory.

Abu Simbel, The axis of the temple was positioned by the ancient Egyptian architects in such a way that twice a year, on October 20 and February 20, the rays of the sun would penetrate the sanctuary and illuminate the sculpture on the back wall, except for the statue of Ptah, the god connected with the Underworld, who always remained in the dark.
The so-called Giants' Churches (Finn. jätinkirkko), which are large, from c. 20 metres (66 ft) to over 70 metres (230 ft) long rectangular or oval stone enclosures built in the Neolithic (c. 3000-1800 BC), have axis and doorway orientations towards the sunrises and sunsets of the solstices and other calendrically significant days. For example, the Kastelli of Raahe, which is one of the largest Giants' Churches, had its five "gates", i.e. wall openings, oriented towards the midsummer sunset, the winter solstice sunrise, winter solstice sunset, the sunrises of the mid-quarter days of early May (Walpurgis, Beltaine) and August (Lammas), as well as the sunrise 11 days before the vernal equinox in 2500 BC.
